MODE oEcoNsTRUcTING LocKs EOE THE DooEsoE BUILDINGS, VAULTS, sAEEs, am.,

AND ALSO THE NIGHT-LATGHES OCCASIONALLY A.ATTACCHIED OUTER DOORS.

TO THE LOCKS OF specification of Letters Patent No. 215, dated June 14,1837.

To all 'whom/,tt may concern Be it known that I, JAMES MCCLORY, of thecity of New York, in the State of New York, have invented,l certainimprovements in the mode of constructing locks for the doo-rs ofbuildings, vaults, safes, &c., and also in the night-latchesoccasionally attached to the locks of outer doors; and I do herebydeclare that the following is a full and'exact description thereof.

The boX, or case, of this lock may be made in the ordinary way, as shown'in Figure 1 of the accompanying drawing, which shows its principalparts, the plate, or cap, which covers the tumblers, &c., being removedfor that purpose. The tumblers of this lock consist of flat plates ofmetal A, A, which lie, and slide freely upon each other; in the lockrepresented, there are six of these plates, but the number may be variedto any extent desired. These plates are all contained in a separate boXB, B, which may be readily removed from the main boX, or case, of thelock, when it is desired to give a new arrangement to the tumblers, itbeing held in its place by a screw button, or cat-ch, on the oppositeface of the lock. The four studs b, b, b, b, constituting a part of theboX B, serve to hold the tumblers in their places, and to guide them asthey rise and fall. The main bolt of the lock, C, has on it a strongstump, D, solidly attached to it, and rising up through the openingsmade in the tumble-rs to receive it; these openings are at differentheights from the lower, or concave, edge of the tumblers, and requiretherefore, to be lifted by the key, to different heights to liberate thest-ump D. The tumblers are lettered or numbered, and may be laced in anyorder that may be chosen.

The bit of the key, Fig. 2, has on it a number of shifting plates, orcams, E, corresponding with the number of tumblers which are to beraised by them, having on them the same letters, or iigures. The lowerpart of the key F, which shoots the bolt is in one piece with itsbarrel. This portion is shown separately, in Fig. 3, divested of thebits, or cams. The shank part G slips into a socket on the upper part ofthe key H, in which it is confined in its place by means of a wedge, orpin, h. The ferrule, i, is intended to slip over a portion of the wedge,or pin, to prevent its accidental removal. The cams are put on to theshank G, at its upper end, and are kept from turning by a feather uponthe shank, fittinginto a notch in the cam., or in other obvious ways.One of the cams is shown in Fig. 4, withla notch to receive aA featheron the shank. Y

I, Fig.` l, is a spring-bolt, with its ap-V pendages, which requires nodescription;

OEEIcE.

but in knobbed locks, I have madeV an imy provement in the manner ofconstruct-ingv and connectincr the knob and spindle 'by which thekspring bolt is to be retracted. One of the vknobs is, as usual, firmlyattached to the spindle, my improvement consisting in a new mode offorming, and giving a'bearing to, the nut by which the movable knob isattached to it. Fig. 5, shows a sect-ion of the knob, with its nut, andspindle. J, is the nut, which is cylindrical for its whole length,fitting into, and passing freely through, the hole in the top of theknob, and its lower end having a bearing within the knob, just where thesquare hole for the spindle terminates, as shown in the drawing. By thisarrangement the upper end of the nut has no bearing upon that part ofthe knob, as was the case in the old method of forming them, while theknob can be forced to such a distance upon Y the spindle as shallcorrespond precisely with the thickness of the door, and the nut, in allsituations, is kept flush with the top of the knob.

On those'locks, or latches, where a night key is to be used instead ofthe spindle and knobs, I have made an improvement by which greatadditional security is attained.

For the purpose of clearness of description,\

I have represented the springy bolt as operated upon -by a night-key andits appendages, as separate from the lock; and it may be so made, ifdesired. The key of this bolt, or latch', Fig. 6, is made in the usualway; the cap, Fig. 7, which is removed tO'eX- hibit the parts which itcovers, has a socket K, riveted on it, which receives the cylin dricaltube L, of the bit M, by which the spring bolt is to be pushed back. Thelcylindrical tube,'L, turns freely upon thel pin, N, and the bit isborne up against the cap plate by a spiral spring which surrounds thepin below it, keeping the upper end of L, flush with the socket K. Thebit may, consequently, be forced downrby the bearing of Cil the key onthe top of L, until its shoulder, 7c, comes into contact with the end ofthe socket, into which its neck, Z, enters. There is a thin plate ofmetal, O, attached to the bit M, which, in order to the withdrawing ofthe spring bolt, Vmust pass through a notch in the stump P, and in amovable racking, p, which is attached to it by a joint pin; and, if akey be used, the neckvof which is not of the proper length, this passingthrough cannot take place, as such key will not bring the two notches tocoincide; when however,

ing the knob to the spindle, by a 'nut made, and operating, in themanner set forth.

the proper key is again applied, it will return everything to its place.The upper end of the movable racking, and its stump,

rangement of the bit, with its tube, and the ,movable racking, in thenight latch; to-

are shown in F ig. 7, by which their mode of action will be seen.

Having thus fully described the construction of my improved lock, andthe manner in which the same operates, I do hereby declare that I do notintend to claim the combination of a series of tumblers capable ofnumerous permutations, and having a key adapted thereto, this being awell lmown device. But

key in two parts, for the'purpose of plac` ing the more movable bitsthereon from t-he upper end of the lower section, leaving that part ofthe bit which'operates upon the bolt,

` in a solid piece with the barrel of the key.

3. I likewise claim the manner of attach- 4. And, lastly', I claim theparticular argether with such variations of these respectiveimprovements as I may deem proper, while I attain the same ends by meanssubstantially the same.
